This world was bizarre. A human wouldn't be able to become a zombie just by exchanging saliva. But if the zombie were to kill someone, and the body was still intact, the 'dead' person would instantly become a living dead or zombie.
That means the zombies didn't need to exchange the so-called 'virus' to turn the other person. Even if the human died, the number of zombies could still increase.
That was why the humans, who were alive now, started believing in cremation rather than burying the body underground.
Unfortunately, not everyone was well aware of this fact. After all, it only had been a few weeks ever since the apocalypse started. So they would leave the dead bodies to rot under the sun. And after a while, it would be horrifying to see those dead people turning into zombies and attacking others.
The situation was even worse when friends or relatives would end up turning into a zombie, killing the ones who used to love the living dead.
